BARREL-HOOP.

Specification of Letters Patent.

Application led February 4, 1907, Serial No. 355,765. Renewed December20, i909. Serial No. 534,162.

To all whom it may concern:

Be it known that l, CHARLES Horn, a citizen of the United States ofAmerica, and a resident of Cincinnati, in the county of Hamilton andState of Ohio, have invented certain new and useful Improvements inBarrel-Hoops, of which the following is a specification.

This invention relates to an improvement in barrel-hoop construction inwhich a part of the metal is projected inwardly from the face of thehoop before it is placed in position and whereby it is designed toretain it in such position against accidental displacement.

The present invention consists of a barrelhoop having on its inner faceone or more spear-head or fore-shortened diamond shape projections orprotuberances each comprising an impressed portion of the metal inclinedprogressively throughout its length and beveled laterally along itssides from a common definite central line or ridge, the latterterminating in a point or horn at the highest part of the projectionadjacent the head-edge of the hoop and extending so as to overhang orjut over the flat body portion of the metal, whereby, when the hoop isbeing driven into place the said inclined ridge forces its way into theface of the bariel and guides the said extended jutting point or horninto anchoring and seating position to prevent backward movement orundue slipping of the hoop from place on a barrel.

ln the accompanying single sheet of drawings, Figure l is a fragmentaryperspective view of one end of a barrel showing the improved hoopthereon; Fig. 2, a fragmentary elevation of the outer face of theimproved hoop; Fig. 3, a fragmentary elevation of the inner face of thehoop; Fig. Vil, a vertical, secw tional elevation on line a0, of Fig. 3;Fig. 5, a vertical section on line y, y, Fig. 3; Fig. 6, a fragmentarysection of a stave showing the device as seen in Fig. 5 applied in fullanchored position; Fig. 7 a bottom plan of Fig. 2, looking upward fromthe bilge-edge of the hoop; and Fig. 8, a longitudinal section on linez, 2, of Fig. 3.

In these views, 1 indicates an ordinary barrel-hoop made of metal, and 2indicates each one of a series of retainers or protuberances made in themetal and disposed lengthwise transverse to the head and bilge edges ofthe hoop. The said retainers project inwardly from the outer face of thehoop and are of spear-head or slightly foreshortened diamond shape, animpression or indentation by means of a suitable tool or between diesbeing made in the metal to produce each retainer. The sides 3, 3 of eachretainer slope laterally from a definite central ridge or line 4 whichextends along the entire length thereof and terminates in a de cidedhorn or point 5 that extends or juts over the plane portion of the metalbeneath. The metal impressed or projected backward preferably remainsintact, as best seen in Fig. 5 and the rear wall 6 inclines to someextent so as to provide a retreat or seat for the fibers of the woodwhen the hoop is driven into final anchoring position (Fig. 6.)

It will be seen in Figs. eland 5 that the face of the protuberance 2inclines from the extended horn or point 5 down to its meeting 5a withthe plane face of the metal, and it will be seen in Fig. 8 that the saidprotuberance 2 is V-shape in cross-section, both of which forms are thedesired ones to be adhered to in the construction of my device. It willalso be seen, particularly in Fig. 3, that the protuberance is ofdiamond-form, but that the end of the diamond bearing the extended hornor point 5 is shorter than that of the other end, such shorter end beingthe anchoring one and it not being deemed nec essary or practicable tomake it longer than shown, as it will decidedly bury itself deep enoughin the wood to prevent any undue displacement of the hoop.

rlhe arrow, adjacent the hoop in Fig. 6, indicates the direction ofdriving the hoop into place on each stave A.
